Thank you for replying to my question. The reason that I beleive that I cannot use an image tag is that I am trying to create a template system, whereby users can design there own websites.
To do this I have created a page with a small table with three cells representing the users web page. In addition I have set the font size relative to the size of the table representing the window using the scale font function.
From within the same page users can select from a number of colors which are automatically displyed as the background color for the table, or certain cells of the table.
In addition I want the ability for users to select from a number of background images, which when selected will automatically be displyed as the background image for the table. The problem being that I can't use an image tag to set the background for all the cells in the table, and whenever I set the image as the background for the whole table the image is not forced to the same size as the table, but rather only displays part of the image.
I should also mention that for the purpose of displying an image I can't change the layout of the table i.e create only one table cell as there is also text displayed in each of the table cells which are also referenced by other objects.
