Easy RSS feed & PicLens

[nuttz]

Nibbler, do you know if there are any plans to integrate piclens officially?

[Nibbler]

No plans. Would be better as a plugin than part of the core code.

[shiftsrl]

If I ever get the time to work on this again I plan to make it work on a per album basis, so your rss file being to large won't be a problem unless you have thousands of pics in a single album.

thanks nuttz for the work. I'll wait for the per album release. in the meantime this one works very well

Hi,

i've installed EasyRSS plugin, replaced rss.php using denisjl's modification.
I found that it's not working if URL is http://www.fotecka.net/rss.PHP?album=91, but if I take a source of URL, put it into file named photos.RSS, than it's OK.
Does anybody know whether Piclens works with .RSS files only?

Thanks

[Iced Coffee]

Guy, the thing wrong here is that you capitalized the PHP in rss.PHP:

http://www.fotecka.net/rss.PHP?album=91

Just try this http://www.fotecka.net/rss.php?album=91

[Iced Coffee]

Here is the file.

I am using Easy RSS plugin and Denisjl's file. PicLens runs fine on my site http://giadinhhanhphuc.net/anhgiadinh/ ; however, there is a problem that though PicLens loaded 300 thumbnails, only 8 first ones (latest pictures) load full size when I zoom in, the others only loaded thumbnail size pictures, therefore, get broken/low resolution when I zoom in. Can any tell me how can I correct it so that all pictures will be loaded correctly? Thanks.

OK Guys,

here is my little easy rss mod.
It's running fine on my Gallery so far. I'm sure it has some bugs left in it  :-\
So please give me a hint on what you noticed. If there are security issues please leave me a Note.

My Albums contain thousands of Pictures so loading all pictures at the same time was no option regarding Server CPU-Load and Download Traffic. The mod loads only that many pictures as there are thumbnails in your Album View on one Page (intval($CONFIG[plugin_easyrss_num])).

I added a few  Comments to the Code to give a little Info about what the Code does. Since i am no PHP specialist i'd be glad to hear from you if you have suggestions on what to change.

To get the Plugin working just replace the original Easy_RSS file (rss.php) with my Code. And you need to add the following line to the Template html Headers:

Code Select Expand

<link id="gallery" rel="alternate" href="rss.php?album=&amp;page=&amp;imgpos=" type="application/rss+xml" title="Image Gallery" />I've done that by the codebase.php with a few more options. But it is not done alone by me, so sorry, i can't give that away, not now.

OK so here's the Code:

[andiwe]

...The mod loads only that many pictures as there are thumbnails in your Album View on one Page (intval($CONFIG[plugin_easyrss_num])).

So the rss feed is very small. If you enter the Piclens Application it will load all Images of e.g. the current Album as you start moving "the wall".

This makes it possible to start PicLens with "lastup" and scroll through ALL pictures in your CPG installation (ATM ~20.000 on one of mine).

So far it's working for Lastup, Topn (most viewed) and per Album.
If you're in Cat or e.g. Lastcom (comments) it will show you to the Lastup feed.

To get the Plugin working just replace the original Easy_RSS file (rss.php) with my Code. And you need to add the following line to the Template html Headers:

Code Select Expand

<link id="gallery" rel="alternate" href="rss.php?album=&amp;page=&amp;imgpos=" type="application/rss+xml" title="Image Gallery" />I've done that by the codebase.php with a few more options. But it is not done alone by me, so sorry, i can't give that away, not now.

Sorry that was #*!&$*# 

Please modify the codebase.php this way: Remove the function easyrss_header and replace it with the following:

Code Select Expand

function easyrss_header() {
    global $CONFIG,$lang_plugin_easyrss;
    require ('plugins/Easy_RSS/include/init.inc.php');

//A/ so here is the Header for PicLens
    $add_header_info = "";
//    $add_header_info = "<!-- Step 1: Add a Photos RSS feed to this webpage. //-->";
    $add_header_info .= "\n<link id=\"gallery\" rel=\"alternate\" href=\"rss.php?album=".$_GET['album']."&amp;page=".$_GET['page']."&amp;imgpos=".$_GET['pos']."\" type=\"application/rss+xml\" title=\"Image Gallery\" />";
//    $add_header_info .= "\n<!-- Step 2: Include the PiclensLite JavaScript. //-->";
    $add_header_info .= "\n<script type=\"text/javascript\" src=\"http://lite.piclens.com/current/piclens_optimized.js\">";
    $add_header_info .= "</script>\n<style type=\"text/css\"> .mbf-item {display:none;} </style>".$otherHead;
    return $add_header_info;
}

Notice the page and imgpos ... that is for jumping directly to the correct Feed-Part and showing up the Picture you have clicked on.

And finally here is the rss.php as attached file.

Hi,

I installed Easy RSS, modified codebase.php with the new easyrss_header() and installed your rss.php file at the root of my gallery.

When I try to access the rss feed, I get a PHP error:

Code Select Expand

XML Parsing Error: no element found
Location: http://photos.reichertonline.be/rss.php?album=42&page=&imgpos=0
Line Number 6, Column 1:

Any idea what is wrong?

Thanks!

[Iced Coffee]

Yes, I was found the same error though I used the previous version (I downloaded 1 month ago I think) and it was fine.

XML Parsing Error: no element found
Location: http://giadinhhanhphuc.net/anhgiadinh/rss.php
Line Number 10, Column 1:

I've just re-uploaded the previous version and it is working well now. So, what's wrong with this new version?

[snark]

I've just re-uploaded the previous version and it is working well now. So, what's wrong with this new version?

Can you please post the previous version or make it available somewhere for download? Thanks!

[Iced Coffee]

Here it is in this zip file

[andiwe]

Please replace Line 34 in rss.php

Code Select Expand

$thumb_per_page = intval($CONFIG[plugin_easyrss_num]);

with:

Code Select Expand

$thumb_per_page = ##
Where ## should be the Number of Thumbnails in your album view.
e.G. if your Thumbail View is 4x5 Pictures the Number is 20

Did this work ?

[andiwe]

Don't forget the ; at the end of the line 

[snark]

Yes, I tried changing that value already (with the ; at the end  ) but no success.

[snark]

BTW andiwe, I checked the RSS feed on your gallery. Is it normal you have 2 media:thumbnail elements per item??? I don't think so.

[snark]

I found the error in rss.php. The error displayed in the browser is actually not in the PHP file, but in the generated XML feed.

To solve the error, change line 305 in rss.php from

Code Select Expand

$picmd5     = getGuid(md5($picture[pid]));
to

Code Select Expand

$picmd5     = md5($picture[pid]);

I'm not sure if there are any side effects to this change. PicLens works fine in my gallery with this fix.

Let me know about yours.

[andiwe]

to be honest, i don't know really what effect the md5 sums have for piclens. i just saw them being generated by the original software. i could not recognize any difference until now. thanks for the fix, i will try this weekend.

the thing with the 2 thumb urls is following:

//A/ i replaced the thumbnails with the normals and the normals with the full sized pics
//A/ thumbnails are looking bad in wall view
//A/ linking in the picture by the icon doesn't work anymore with that option :-(

//A/ as you can see i now have 2 thumbnail urls
//A/ only the first will be used to load the pictures
//A/ the second one is to publish the real thumbnail filenames to piclens
//A/ without that the play button won't appear in the thumbs in album view.

just change it to your needs 

BTW: what $thumb_per_page value did you use in your galery ? 25 should be fine, perhaps decrease your value to that to make the play buttons on further thumbnail pages visible.

[snark]

just change it to your needs 

OK, thanks for pointing to the explanation. It works great like that and makes browsing my albums a real pleasure!

BTW: what $thumb_per_page value did you use in your galery ? 25 should be fine, perhaps decrease your value to that to make the play buttons on further thumbnail pages visible.

Yes, I just set it to 25, the number of images per page in my albums.

[Iced Coffee]

So can anyone post the final version of the rss file? Is there any difference between this one and the one I attached in the earlier post? Thanks.
