I would rather suggest to add the location under Texture in Tools > Options > Files location so that those appear in the Appearance folder in the taskpane and you can put them as surface texture.
You might also find this post helpful for your future reference.
cheers for your response. is that the only way to achieve this, as i was sure i could do it as a decal? would be much easier lol.
Hi Luke, try turning on your render tools if they're not active.
(RMB on the bar at the top of the screen and scroll down to "Render Tools", LMB on the icon to activate.).
The third icon in is to Edit Decal, click on this then Browse to the file location for the image you want to use.
Click on the face you want the decal, adjust to suit etc..
I hope this helps
cool, all of you guys have been a great help.
Adrian your awnser was perfect! its actually easy once you know what your doing too lol.
so here is where im at. I managed to get round the issue and am now able to add custom decals. however, once i had my new decal selected, i then went into the mapping window to select the surface i wished to pace the decal on (i.e. the front screen). initialy i had the problem that, despite selecting to pace the decal on a single face it still insisted on covering the entire part. i managed to get round this by first slecting the desired face, the adding a reference and selecting the same face. im sure this isnt the best way?
also (as if im not a pain enough) i have deleted the decal, and though under the decals tab it now says "no decals assigned" the image still displays on the screen! (see attached image) a little confused??? lol
p.s. please excuse my amatuerishness!
