Do you take pictures with a cell phone? You could email them to yourself, and either save the photo to your computer, or right click "copy image address" and paste that into your image host site.
Or, if there is a micro SD card in your phone, and your computer has a port for it, then you can plug in the SD card. (Or, your phone should have come with a use cable, and you can plug that into the computer.) A folder for your phone should open. You may have to dig around a bit to find the folder with your photos. Once you do, drag & drop them into your computer. If a folder doesn't open on it's own, pull up "this pc" or "my computer" and you should see your phone under "devices and drives." You can open it from there.
If you have a digital camera: it should also have an SD card inside, which you can plug into your computer if it has an SD port. (Or, a digital camera should also come with a usb cable to plug into your computer that way.) Then a folder with your photos should open, and you can drag & drop them into your computer. If a folder doesn't open on it's own, pull up "this pc" or "my computer" and you should see your camera under "devices and drives." You can open it from there.
If your camera is a DS, then you'll just need to pull out the SD card and plug it into your computer. A folder for your DS should open. You may have to dig around a bit to find the folder with your photos. Once you do, drag & drop them into your computer. If a folder doesn't open on it's own, pull up "this pc" or "my computer" and you should see your DS's SD card under "devices and drives." You can open it from there.
Or, if your computer does not have an SD card port, you
may be able to email the photo to yourself from your DS. Pull up the browser on your DS, then navigate to your email. Attempt to attach an image to your email. I fit lets you choose an image stored on the DS, then you're good to go. Send the email to yourself, then access your email from your computer and save the image.
If you have printed photos, for some reason, then you'll need a scanner. If this is the case, and you have a scanner, let me know and I will go into more detail
