Hi - Just thought i would share this.
I've noticed that when developing on the imac - that if you load a sprite using the command loadimage(100,"AH.jpg") (ie - Upper Case AH in jpg) and the image in the media folder is named ah.jpg (ie - Lower Case ah in jpg)
that the application will still compile on the imac and the images will display OK in the app.
If the app is exported as HTML5 - the images will not display ok, ie a Black and White image with a red cross in it is displayed.
One to keep in mind. Beware the case sensitivity in the loadimage command and in the filename of the sprite - when exporting in HTML5
Cheers
