Welcome! That's awesome and of course it's alright with me. So you're making a Sandalorian or a Sandalore? Sandalore=Mandalore... if that helps.
It's very simple to upload large file photos.
Step 1: create a Yahoo.com account. I have one called ActionfigEmpire@yahoo.com
Step 2: head over to Flickr.com and log in using your Yahoo ID and Yahoo account password
Step 3: Follow Flickr's registration process
Step 4: once you're registered click the "You" drop down menu at the top left of the page and select "upload photos and videos"
Step 5: follow the easy upload steps and add the photos you want to your photostream via the uploader
Step 6: once uploaded there will be a button at the bottom of the page that says "add a description?" click this
Step 7: You will see your photos in medium scale thumbnails, look for the first photo you want to post and click on it
Step 8: Your selected photo will appear before you, this time larger, click "share" above the upper left corner of your photo
Step 9: Click "Grab the HTML/BBCode" option and then select the "BBC" radio button.
Step 10: Highlight the code in the box and then hit "Ctrl+C" to copy the code for the photo
Step 11: create a new post here on this thread and then hit "Ctrl+V" and paste the BBCode here in the reply text box.
Step 12: select your next photo from the photos to the middle right of your photo on Flickr.
That's how I add mine, good luck!
