Column data contains the filename of an image file to display in the column. Supports JPG, BMP, PCX, GIF, TIF, PNG and ICO file types but requires the A-Shell Imaging Library (an add-on module). You must also specify the options ImgSiz, ImgCount, and optionally ImgDir. You can include arbitrary text in the cell, along with the image, by appending a comma to the filename, followed by the arbitrary text. The column definition has to be wide enough to include both the filename and the desired display text.
Note that although image cells can display additional text, and the text may be made editable (if the column is editable), the image filename itself is not editable. To change it, you need to programmatically change the filename in the column data and reload the tree.
Note also that in the case of ICO files, you may either specify the .ICO file itself (as with the other image types), or you may specify an icon resource using the resname::dllname syntax.
