Title: Image brightness changing upon upload
Post by: dleewo on September 03, 2004, 10:53:12 PM
I've just started playing with CPG today and I noticed that images I upload seem to display much brighter than the ones I originally uploaded.

E.g, I have an image that I resized to 600pixels wide.  If I upload it and display it with Coppermine, it is much brighter than if I display the original local file in a browser.

Thinking it might be a color-space issue, I made sure to set the JPG color space to sRGB, but that didn't help.

If I right-click on the image in Coppermine and save it and then display that in a browser, that image is also displayed much brighter.

Is some kind of processing done on images when they are uploaded, e.g, does Coppermine try to do any auto-levels, or something similar?  If so, can I disable that?

Here is the IMG link from the HTML source:

<img src="albums/userpics/crw_0936_f6.3_640s_iso200.jpg" width="600" height="400" class="image" border="0" />

Is that what you were looking for?

Here is the original image that I just FTPed to the root of my website for comparison:

Interestingly, if I go straight to the Coppermine image via:

http://www.photosbyderek.com/gallery/albums/userpics/crw_0936_f6.3_640s_iso200.jpg

The image is displayed fine.  Maybe something in the "IMG SRC" link is cause the image to be changed? The class?

Please disregard this....it turns out to be a browser caching issue.  I had made the image darker and uploaded a new one (deleting the previous image), but when I reloaded the web page, IE displayed the original image.

Sorry for wasting your time......

No problem.  Case closed.
