I have this bug as well
I have this bug too with some comics, seems like the brightness has been diminished (white appears gray).
MBP, Mac OS 10.4.11 with ATI Radeon X1600 on a 24" Cinema display.
Likewise, also on a MacBookPro running latest version of Leopard 10.5.7
I also have the same problem. I've tried looking the jpeg files in preview or in Photoshop without problem. When I tried to compare the jpeg files that work with Jomic and the files that does not, I can't seem to be able to find the difference. Very strange.
I finally figured out why some jpeg files within the archive show up very dark in Jomic. It turns out that any jpeg files saved with an embedded color profile will have problem with dim display for Jomic. In order to remove this problem, you will need to re-save all the jpeg files within the cbr or cbz archive so that they are not saved with the embedded color profile. I hope the next version of Jomic can get this problem resolved.
It seems Java's ImageIO does not take the color profile into account: http://stackoverflow.com/questions/1271658/why-java-imageio-flattens-jpeg-colors
It's also possible that Jomic accidentally discards the profile, though I have yet to find information on which steps would be necessary to preserve it.
There is a somewhat unsatisfactory solution to save the profile, which could be relevant for converted comics: http://stackoverflow.com/questions/5586671/saving-colorspace-in-jpeg
Maybe this is a Java bug which got fixed with Java 6: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6372769
Can someone having this issue confirm this?
