Here's an example. The image is very grainy, like the sharpen tool was applied excessively. There is a waffle pattern on the label which is artifact. The original image is very smooth and clear. It's puzzling. I didn't have this problem before.



Below is a simple screen shot I uploaded, without optimization, but doing it this way makes the image too blurry. It's weird that the optimization/resizing is creating this distortion when it didn't before.

I use PS CS5. I can change the pixel size in CS5 to lower than required on the Optimizer, but when I try to upload the image the optimizer says that it's still too large. So I optimize the already reduced image, and it still comes out distorted. Now, If I go even lower, to a 700 pixel width, for example, then the image will be correct, but it will then be too small overall. It's crazy.

I guess I'll just have to play with it a bit.

When you save the file in Photoshop, choose Save for Web, or save it as a .jpg -- when you choose to save it as a JPG it should pop up a box with quality information. Adjust the slider from 8-11 or so until you see a displayed file size of 275k or less (I use CS2 and it tends to underestimate by about 25k.) Save for Web uses ImageReady to convert your .PSD to a .jpg and allows you to also see the file sizes.

I find that image sizes of 1000x1000 or less work best.

The "pixellation" effect is a function of DPI or dots per inch. Most pictures I run across tend to be around 75dpi. I shoot in 300dpi.
The higher the DPI, the more scalable the image is - you can make it, say, 2000x2000 and not lose detail vs 1000x1000, whereas some low-DPI images can be great at 300x300 and look like Minecraft at 600x600.

This screenshot shows you the Save As -> .jpg slider. It may be different appearance in CS5 but the functionality should remain present in some form.
