I have a gallery that reads an ms access database using asp and then loops through an array of records and duplicates an empty movieclip for each record.
A jpeg is then loaded into the movieclip and then a variable for the _x position is incremented and then the next one is loaded etc.
I then use the same method to add the necessary labels for the images by duplicating a movieclip and adding a text field.
This is all fine and produces a gallery of images but the problem comes when I try and position the labels according to the height of the image. I have tried every method I can think of to check the image attributes which are only available when it is fully loaded, but I keep getting a value of 0.
The code is below. Any help would be greatly appreciated - thanx
