Re: [WSG] Image Thumnail Advice
A big thanks to all regarding all of the advice given on my image-reduction issue. I have tried a number of the suggestions and - depending on the color depth of the different sites I'm trying to reduce - the results are much more favorable than previous to my post. I know that one of the WSG admins would like to close this topic - because it is off topic, so I just wanted to say thanks for everyone who did weigh in on this issue for me.

If you're on a Windows box then you're quite possibly dealing with conflicting image resolutions. If you create a new image in Photoshop you'll notice that it's most likely set to 72dpi. I believe Windwos default is 80(?). I then recommend using the Image->Image Size... menu item to resize images, not Transform->Scale. If you're going to use a sharpen filter then go with Unsharp Mask ona settingn of about 150%, 1.2px, 7 threshold. You can then simply Ctrl-F to apply Last Filter in order to increase the effect if you want more.

Ok, enough on that thanks. This is a 'PhotoShop how to' rather than a Web Standards discussion. Peter

You wrote: >> 3. paste the capture into PhotoShop 4. Transform/Scale the image from it's captured size (760 pixels x 550 pixels) down to a 165 x 115 pixel thumbnail >> First, don't use transform/scale. Use the Image...Image Size command. It should already be set correctly to 72 dpi, constrain dimensions (checked), resample...bicubic (checked). If not, make it so. Now, resize in steps. If you're starting with 760, half it. Now resize again at least once more. I'd probably divide the max dimension into three or four and resize it progressively down. Next apply an Unsharp Mask (Filter...Sharpen...Unsharp Mask). Somewhere between 50 and 100% should do the trick. Every once in awhile there is value to sharpening after each resize. It depends on the image. You could also use bicubic sharpen but honestly I usually see better results with a sharpen only applied on the final image. Alternately, if you're trying to include thumbnails of screenshots in a print portfolio (?), go to Image...Image Size and change the resolution to 300. Keep the constrain dimensions checked, but this time change the resample dropdown to "Nearest Neighbor" (checked). This last part will avoid anti-aliasing. Key is saving it as a TIF or similar at this point...If you "save for web..." you'll end up back at 72 dpi. Jona Web Services ME&A

Use save for web then use the resize tab below the output options. Chose jpeg medium from the top. Should be good quality output.
