Greetings... I am using three frames to create a user interface for some product information, with one frame (left) containing JS animated buttons (each a series of products) that call into another frame (bottom) another series of buttons (the products in each series), each of which puts an image (product info) into another frame (mainframe) using target. I have everything working except for a flashing of the image everytime a new HTML product info JPG is loaded by bottomframe into mainframe (using a basetarget header tag). Is there any way to preload all images into one HTML doc and put it into mainframe and control it from the JS buttons in bottomframe? Would/could I use hide/show or Z-order/bring-to-top to get around this? Meta tags for filter/transitions don't work across frames, evidently, and I am stuck here... Not a good enough JS programmer yet, I'm afraid... Walls.
