The maximum recommended width is 800 pixels (600 is better as some people are still using 800x600 resolution). The best formats to use are usually transparent GIF or transparent PNG (smallest if few colours are used). JPG images with text are not so clear unless saved at the highest quality, so use GIF and get the additional advantage of transparency.
Large images slow down the loading of threads, so crop the image or resize the application window before taking a screen grab with Alter Print Screen to show just what you need to illustrate.
Linking to Files
Upload a font or other file to your webspace and link to it with code like this:
(url=http://homepage.ntlworld.com/pesala/Fonts/TUFFY6.zip)Tuffy Truetype Font(/url) (60 Kbytes zip file) but with square brackets will display an active link to a file.
People who don’t have a access to a personal web space or don’t know how to do this, can send their screenshots/ fonts directly to me and I’ll upload them to the forum.
The latest release of Irfan View 4.0 has a plugin for uploading files to a server. Select the files in the thumbnail browser, and from the file menu, select “Transfer Selected Files by FTP ..”
Enter the server name, user name, and folder (these details are remembered), and your password. Thereafter, you only need to enter your password.
If, like me, you often upload images to illustrate a point, this saves loading an FTP program.
