I find that many people opt for full transparency when applying images/graphics to their forums. This is fine, if that image hasn’t got any curved areas or transparent areas. However, Opting for full transparency when dealing with curved images results in that image having a jaggy border showing around it which gives that image a rough taccy and sometime redundant colour around the edges. if you’ve not used the correct matte colour to compliment the background colour to which the image is being applied onto basically it’s going to look shit.
I find that using the matte dropdown menu in photoshop and picking the appropriate colour background that the graphic is being applied onto eliminates the rough graphic which has become more commonplace. Using this method, will result in smoother more higher quality displayed images whithout that redundant edge looking so nasty.
You have your image/graphic completed, and you are ready to save and apply that image to your forum and/or website.
1. In Photoshop. Click File scroll down to Save For Web, Select and click.
2. Now that you are in the Save For Web menu. Follow the instructions showed in the screenshot. Bare in mind, that the color you choose for instruction no 2 is the colour of the background that the image is being applied onto (the background colour it’s being applied upon). Step 1 is your format selector which would only apply if you choose .gif. (Screenshot Below)
An example in using .gif and saving it to a matte colour, rather than saving it as transparent, you’ll see the visual difference in quality. Correctly colour matted .gifs will look visually superior than transparent .gifs which results in jagged edges (around curved edges) and parts of the images being cropped.
Finished. You should now have a smoother, visually improved looking image applied onto your forum or website. Bare in mind, this applies to .gifs where .gif would be the preferred format over .png due to the icon containing animations which .png doesn’t support though .png does a better job with transparency and I would recommened using .png for static images.
