Creating PCT images & Editing in HyperCard

I've been looking into converting current formats like .jpg into .PCT format to import into HyperCard to be manipulated or drawn onto and made into icons for buttons etc.
A bit of a meandering process that turned out to be much easier than I expected. Reading info on the web gave me the impression that converting file formats to or from .PCT would be difficult - turns out you can use GraphicConverter to do this in no time at all. I remember GraphicConverter from years ago (though not as 'front line' graphics software) - something I hadn't considered using. Whats nice is it happens to be another historic piece of software for me to look at. Anyway, some examples:

Using the paint tools in HyperCard takes a little getting used to, as they're similar to what you find in Photoshop these days but selections and layers (there are only two) work quite differently...This means you find yourself un-doing things a lot because you undertake tasks as you would in Photoshop only to find yourself in a cul-de-sac. There are also some extinct niceties to take advantage of in HypwerCard - the above used the 'lightening' and 'trace outline' commands on the PCT once it was pasted into HC.

Creating and editing icons isn't headlined in the 'getting started' info all that well. The above uses a 40x40px PCT as reference, edited with the Icon Editor - a pencil to go DOT DOT DOT with...
