speech bubble question/image

[asripuram]

Hi,

I'm creating an interactive handset training guide for my clients and I would like to add some callout (speech bubbles) to the guide. However any image I create in Photoshop (5.5) seems to have a white background so when I place the image over a photo in the guide (for example) the white background gets in the way. Can anyone suggest a way to create the image either in AMS or in Photoshop which doesn't automatically fill in the background.

save the image as a PNG-24 with a transparent background

Photoshop 5.5 has sketchy PNG alpha transparency support, seems to me it was via a sort of akward plug-in looking Adobe wizard which never got perfect results. I would recommend using a more modern image editor for exporting PNG with alpha, there's probably a few decent free ones around if you check Google...

FWIW Macromedia Captivate has a built-in means of creating these bubbles / callouts.... the Captivate files may be exported to .swf and then imported into AMS...

Doesn't AMS have an option to set a certain color as transparent on an image? That'd be the easiest solution.

Not if you have semi transparent (read alpha channel, Anti-aliased boundaries) image. Then the background color "leaks" through.

Wow,

That transparency property is exactly what I need. I can capture the speech bubbles from powerpoints collection of callouts. Then (as long as my speech bubble is in colour, i can use the transparency property to make the white background transparent.

Perfect!!!

Thanks for all your help!
