Hey there,
If you can take screenshots or pictures of your drawings, save them then send them to yourself via email. Once you have the files, upload them to an image uploader. You can then use https://postimage.org/ to upload your images or something like that. Once it is uploaded, simply take the Direct Link and enter it into your post and the image should automatically populate. I hope that makes sense and good luck.
Thank you my friend. I had never heard of an image uploader so I was rooted from the start. I'll let you know how I'm doing. Cheers.
