Placing an image on the bottom of the PCB

[Pedro147]

I have used Eagle a few times before and successfully added an image to the top of the PCB, but have had difficulty doing the same thing on the bottom.I made a library package, generated and  ran the script to render the monochrome bitmap image into the lib pac. I set it to layer 26 bottom names, but found that I had to use a mirror image to get the logo, which is symmetrical but has text as well as a graphic component, to display correctly. It appears to have worked OK, in that when I set only dimension (20) and bottom names (26) layers it is displaying correctly. in the Eagle board view and also when I put the board file into a 3D online viewer and rotate the image to show the bottom of the board. The other perplexing thing is that the origin  is showing in the top origin  (23) layer not the bottom (24)  Would somebody mind taking a look at my files and seeing that I am doing this correctly before I submit to design to a PCB manufacturer. I hope that I have provided enough information for someone to take a quick look but if not I can provide additional information as required.The Eagle sch brd and lib files are hosted on my Mediafire account at the links below.

Thanks for you time and advice Pedro..

When I import bmp files that I want to end up on the back of the pcb I just import it to tPlace (or the default Layer 200 and change it to tPlace after checking that the image is of correct size) and then I select the image as a group and ctrl-right-click to mirror the group.

Thanks  matseng. So regardless of the layer, the image must be reversed must it

[matseng]

Make the image normal (so you can read it).   Then import it onto the top of the pcb. With the "mirror" command in Eagle it will be moved to the bottom layer and at the same time automatically be reversed/mirrored so it will end up fine on on real pcb and in a 3d-gerber viewer.

Thanks again matseng I have done as you said and I will remember next time
