it has nothing to do with your image, should be because of your code.. cause no matter what size you have, you can always display an image propperly.. so it's most likley your code that isn't correct..
Ok, I've tried this. For example, a 12% height worked on the first page, but not on any of the others. When you do it for height the length of the ever-changing pages must be taken into account. I am looking for a more permanent solution then that. Cause with this method, rather then having a php file that I include so I only have to change one file, I have to manually edit about 50 pages, and keep doing that over, and over. Can anyone offer a more permanent or feasible solution?
What I saw in your problem was really on coding.
I'm in a graphics for almost 6 years and i'm still in here.
Try to figure this out;
A picture or banner created with 1 inch by 5 inches (1X5) equals to 100X500 pixels and with a resolution of 300dpi being sent or uploaded in the internet, let say in My Space. When viewing on that page (My Space) it look good and very well. But if you try to download it the result would be a big difference. From 300dpi it would turn to 100dpi and sometimes 72dpi depending on how it processed from My space.
Now about your problem, if you are using photoshop, it would be the same resolution if you upload a picture or banner with resolution of 300dpi and never put any size on your codes. Because the moment you put a code that is below or lower than the exact size of the original image it will start decreasing its pixel and resolution and will never return to its original size with the same resolution. It will probably give you a 30% less resolution depending on how you resize the image. The more you reduce the size the lesser the chances to return to its original pixel and sometimes the result will be GARBLED images.
1. always put your image as it is or WYSWYG. If you want to fit it in your page
2. Never resize it by using codes.
3. resize it by WYSWYG editor or any image editor.
I just hope it will you a lot in your problem and in your future sites.
