Greetings everyone.

I’m trying to take pictures of original artwork and optimize them for a website. The medium the artist uses is a bark-paper that has edges which I can only describe as similar to the egde of a hole in jeans after they have been washed a few times. Because of these edges I can’t have a solid background.

I’ve removed the existing background to a transparency and use the ‘save for web’ option. Obviously I want them to be jpeg’s, and am trying to get them to the <20k range, but this is where I encounter problems. I’ve tried the ‘matte’ (matching the matte color to the web page color) option, as well as using the web page color as a background on a different layer but I always end up with a halo effect. My guess is that the matte and/or background layer quality is being lost in the optimization process…

Can someone point me in the right direction or am I just sol?

Thanks folks.

There are a number of alternatives. One is to use png, which allows you to represent true transparency on a web page image, modulo the matte color. Another is to use a transparent GIF, which may not look all that bad depending on the type of artwork.

Finally, jpg should work reasonably well, provided you match the background with a web safe color. You may be running into problems with the mask being generated incorrectly – for example with the magic wand tool with no anti-aliasing, or the tolderance set too small.

It would be informative if you posted a link to one of your images.
