does anybody know how to make the photos really small in terms of bytes, yet still retain their quality? does it make a difference if the file is digital or a scanned print? (mine are scanned RC prints @ 300dpi). thanks!

Dear Jon, it is very tough to amintain the quality when u r reduing the size..in bytes...still you can limit the degradation ... to some extent...if you do not...cross the limit...and you can experiment...first for example...reduce by 70% or so...depending on the initial size of the image...then if you are not satisfied just undo...and reduce more or less depending on your choice...another rhing..you have mentioned about the DPI thing...300 DPI is not needed for web or just electronic viewing ... 72 is enough...anyway...do ahead if you think your pics deserve the higher DPI...:) thanks

thanks. just to clarify, i originally scanned the photos at 300dpi and later reduced them to 72 ppi on computer, AND optimzed (reduced) the size of the image for the web. they are still a little big, without a dsl or better conection.
would originally scanning them at 72dpi screw up all the detail, or make no difference?

Scannig at 72 dpi vs 300 dpi will give you less detail...usually better to scan your images at the highest quality possible and let your image editing software resize them...I use photoshop and set the jpeg quality to 5, you have a pretty good balance between load time and image quality that way..in my opinion. (If you want to see how it works you can see my site at egphotoimagery.com) The only other way to make a site faster is to only load the thumbnails onto the page and then when a thumb is click either open a new window or load the pic into the current page at that time. Then you can use higher quality images for your previews. Hope this helps...
