different watermarks for high and medium quality pictures?

[alexandre596]

I know I'm making a lot of topics lately, but well, I just like to chance a lot of my coppermine ;P

my question is: is that a way use one watermark for pictures with width over than 1000 px and another watermark for pictures with width lower than 1000px?

I know it should be around include/picmgmt.inc.php file, but don't know who to do it

thanks

If you just want to use a smaller version of the same watermark image for the medium size pics then just use the downsize function (config).

it's not the same, they're different
they're on the same place of the image (bottom left), just the watermark image that it's different
