SVG compatibilityI'm not familiar with Inkspot. However, I thought I would mention the caveats associated with two of the formats it supports: SVG and PNG.

To my understanding, Opera is the only web browser which offers native support for both SVG (if not part of the current version it is intended for planned upgrades) and PNG. Other browsers can implement SVG support through the use of free plug-ins (available from Adobe). But, as with any plug-in, there are always problems with installation, compatibility, bugs, etc, and, depending on your browser and version, full support may not be realized using this (plug-in) method.

The main problem with PNG is that it is not fully supported by Internet Explorer. Those of us who have seen the light and switched to Opera, Firefox, or other W3C-compliant web browsers will not be affected. However, with anywhere from 65-90% (depending on the source quoted) of people still using Internet Explorer, the inability to access PNG's alpha-transparency is a major headache for web designers and users alike. In most cases, it has resulted in designers either overlooking PNG altogether or forcing them to create two separate versions of their site graphics - one for those supporting PNG and another for IE users. Of course, many already do this, maintaining separate versions of their sites because of IE's lack of compliance with CSS 2 and other W3C specifications.

That aside, I think I'll take a look at Inkspot's specifications and, if it looks appealing, give it a try. I presently use both Paint Shop Pro and Photoshop Elements, but I'm not adverse to adding another program, especially if it offers features or benefits the others don't.
