    I am trying to reduce the size of a web page I created because it says it will take five minutes to open on a 56K modem. How can I reduce the size of all my jpeg's as far as possible while still maintaining decent quality. Would it be better if they were all thumbnails?

    depends what the pics are

    try experimenting with the thumbnail settings
    - 250 wide
    - 200 wide
    etc

    can you split the pages up more - less info/graphics per page
    - make 3 or 4 pages instead of one big one?

    i try to keep the page load under a minute - more like 30 - 40 seconds - at 56k

    can you upload a sample website/page for a look? and post the url?

    btw - just noticed a few other posts and replies - will get to them in the next little while - still early in mountain time
    also - maybe keep them all in one forum - development usually - so they don't get missed and you get consistent responses

    thanks...to tell the truth I was unsure where to put these particular issues...they sort of cut across different areas...

    I will try putting them on different pages; good idea! Why didn't I think of that....

    I will send you the link to the site soon. THanks for the help.

    What graphics program do you use to edit photos? Most have options for setting the compression on a JPG.

    If you have the original photo in a TIF or other uncompressed format, it's best to start with that (for any of the tips I list), and then create the JPG from it, trying different compression settings until you find the right balance of size and quality. If you start with the JPG, you will have already lost some detail, and the results will get progressively worse with each save. At the VERY least, start with the original version of the JPG each time. Never save it as JPG, make changes, save as JPG again, etc. The file will start looking very bad very fast. Some programs have very nice preview screens where you can try out different settings without saving the image each time

    Other tricks (used alone or in combination) to reduce size :

    1. Crop the image and resave
    2. Resample/Resize the image to smaller dimensions (resampling is the better choice, if you have that option)
    3. Use one of the newer programs that allow you to compress certain areas of the image more than others, so that you can retain quality in the important areas, but allow detail loss in the background (called selective compression).
    4. Use thumbnails on a "gallery" page that point to the larger image, so your visitors can decide whether to get that big file.
    5. Reduce the color depth to lower 24-bit (required for JPGs)setting

    I have used a number of lower-end graphics programs, and I find I like Paint Shop Pro and Adobe Photoshop Lite (now available as Photoshop LE) the best, though there are other good choices.
