What error are you receiving?

1103

Do you get any description? If you could provide a screenshot that would be very helpful.

Is your 1103 error happening when you try to upload the image? 1103 is the code for insufficient storage space. You're very likely up against your limit of 5MB storage.

If this is your problem, then you will need to either delete files you are not using or shrink the files that you are using (or do both).

Texture images should match the size of the UV map they are tied to... This means that they would normally be 1024x1024 or 512x512 pixels, but this depends on the part you are working on. If your images are larger than this, then they will quickly eat up your storage space.

You can try tinypng.com to optimize your images. It is free to use and can greatly reduce your file size, which will allow you to squeeze a larger quantity of files in the same amount of space.

Did you know if you delete a part that the texture image remains in your storage? If you have unwanted textures taking up space, you'll have to remove them.

Here are some links that can help with texture management.
Managing your textures
Deleting parts (and textures)

How do you remove them?

Nevermind, Got it!

I wanna report a bug of the custom parts, i was making a custom face but, the texture bugs terrible!

how do I send a capture to show it?

@Alex-

Here's the link that will show you all of your formatting options for forum posts on Mecabricks. [url]https://www.mecabricks.com/en/forum/topic/14[/url]

For images, you will need to host them somewhere like flickr, imgur or imgbb. Your image hosting site should have a way to grab a link using BB Code. For example, here is the format for Flickr, the one I use:

And this is what you get (an image showing where to copy BB code in Flickr):
