since I’m using mac I click on os, 24bits
Try turning off any anti-aliasing …
Also try saving it as a Windows BMP and not an OS/2 BMP.
You can simply rename the file to a zip extension, i.e., test.bmp > test.zip … don’t actually zip it, just rename it … when it’s downloaded, change the extension back to .bmp.
still not working turning off the anti aliasing and changing it to Windows BMP
trail2.zip (6.6 MB)
The left-hand side had no border … I added a red border (easier to see than white). Try this image (not sure why the file size is different):
trail3.zip (5.0 MB)
I think the problem is when I save the file in illustrator as a .bmp… for some reason sketchup doesn’t recognize my .bmp files. I’ve tried with other files and it works. The one you sent, opened perfectly
could you check this one please
wall001.zip (7.2 MB)
Your wall001.zip file is not exactly black on white:
I changed the properties to B&W and back to RGB and then saved it as a 24-bit color bmp: wall001.zip (5.4 MB)
When importing it, I selected the 
option and got this result:
According to the console output:
Depix removed 2 pixels total (2019-07-24 06:49:25 -0700)
197 Loops Completed (2019-07-24 06:51:13 -0700)
I haven’t been able to resolve the problem. I don’t have windows paint, I work with os and the program I use is illustrator. I’ve tried every suggestion you’ve told me, with no luck. I can only open the files you send me. Can you try make a .bmp texture with illustrator please.
I use inkscape to convert an image into dxf and convert into svg… https://www.youtube.com/watch?v=as0b8GG-0kc
If you use Illustrator, just trace the art and export a DWG file. That you can import and extrude in just a few seconds in SketchUp. You don’t have to mess with importing bitmaps with an extension to do what you need.
I’m sorry you’re having problems … I don’t have a Mac or Illustrator so I can’t help in that regard. You can also use Gimp: open file, change image to grayscale, set b&w threshold, change image to RGB, and export as a Windows BMP. This works with the BMP plugin.
There are other options (as @monospaced or @kenancakir have noted). However, if you don’t have Pro, I don’t believe either of these alternatives is an option without an additional plugin.
If you’re dissatisfied with the plugin, please return it and I will cheerfully refund your purchase price

It’s not really a Mac or Illustrator thing. The whole workaround using bitmaps and a plugin with Pro seems a bit complicated.
I was able to take your original Illustrator PDF, export a DWG, import it into SketchUp Pro and extrude parts with ease. There are a lot of pieces, but the process works perfectly without any extensions or plugins.
There is a free plugin for converting png images with transparency into mesh…
