Dude that is a huge difference, why do you need two sizings that far apart? A dime bag is like, half a gram, and an ounce is 28 grams. That is about 56 times more weed... Also, you could very easily find some pics if you just browse around some other sections, particularly the Stash Jar and what not. But I do understand being new/confused, so good luck to you in the future!
If you're trying to compare what you have to pictures, it's not going to do any good. Even specifying "low grade", weed comes in many different densities and consistencies. A half ounce of really dense weed might look like the same amount as an eighth of really fluffy weed. Pictures aren't going to do you a bit of good, man. Get a scale.
