As of tonight, you should notice a fairly significant speed boost while browsing pictures. Since the introduction of RohJuh.com V4, all scaled pics (the thumbnails as well as the 640X480 resized pics) have been scaled at 100% image quality. This resulted in fairly large image sizes (from a file size standpoint).

After some experimentation, I found that a setting of 80% image quality results in significantly smaller file sizes, but with only a barely noticeable degradation in image quality. Placed side by side in a blind comparison, it is unlikely that any but the most discerning eye would notice a difference. Typical file sizes for the 640X480 resized pics have been reduced on average by 75+%, from ~300-350 KB down to ~70-90 KB. That means that the time it takes to transfer a pic from the RohJuh web server to your computer should be about 4 times faster than before. I’ve tested this with an off-site computer and the difference is substantial. Stepping through pictures is now a much more pleasant experience!

My iMac spent the better part of today rescaling all the pics (over 11,000 so it took a while!). Now, everything’s good to go. Unfortunately, the speed boost does not affect the full-size pics or movies since these are in their original formats and not scaled. The only way the transfer speeds of those will improve is with faster broadband.
