This is a dumb question, I know, but currently there's no way I can edit pictures into Infoboxes and that's really unprofessional. It's one of the only things keeping me from sending a request to be Content Moderator. You see, here's my problem: First I download the picture I later want in the infobox. Then, When I'm editing the Infobox, I type (for example):
File: Yoshi Egg.png (or) File: Yoshi Egg.jpg (depending on if its png or jpg)
Anyways, this worked the first couple of times I tried this but some day, it stopped functioning and I don't know if I'm doing it wrong or if there's something going on with my Laptop. Please answer and tell me how you edit pictures into Infoboxes the way you would too. Maybe there are also things I should be aware of that I didn't know already too.
I think I need a little more context in order to fully help out. What pages specifically were the images not working? Were you putting them into the image part of the infobox or just on the page in general? Were they not functioning in the sense that the images are not showing up at all, or just not showing up in the infoboxes?
If you want to know how I do infoboxes, I specifically edited the Birdo Egg page as a reference point. Let me know if that's helpful for you.
If any other information is needed, I would be glad to provide it for this situation.
I meant that I can't put pictures into infoboxes. Everyything else works as you just have to upload the picture and then place it on the page. In the infobox from the Birdo Egg page it writes:
That makes me ask this: do you have to write the size (for example 250px) of the picture? And also, those double brackets at the beginning and end, are they necessary? As I mentioned earlier, editing images into Infoboxes once worked for me, and I didn't write the amount of pixels or those double brackets. Now my last question: Do you have to use those underlines_between the words?
The way that the infoboxes are integrated into the wiki makes it so that you only have to put the name of the file into the image location of the infobox for it to work. The outside brackets are not necessary when adding an image to one of those infoboxes. Adding the brackets does nothing to the image, but I just do it because not all wiki infoboxes work this way. The 250px in that image is indeed necessary, not because it is changing the size of the pixels, but because that's just the name of the file. If you're talking about changing the pixel size in terms of something like the addition of "400px" to the end of [[File:250px-MKDD Birdo Egg.png|400px]], then that is not necessary for the infobox.
As a simpler explanation, within the infobox itself, using just File:250px-MKDD Birdo Egg.png will indeed create the file, since the infobox is set up to do so. Outside of an infobox, it needs to have the brackets, like [[File:250px-MKDD Birdo Egg.png]], to create an image. Again, I just put brackets on all my files, since every wiki does the process differently.
As for the underscore (_) question, the site as a whole treats spaces and underscores for images as the same character, meaning [[File:250px-MKDD Birdo Egg.png]] and [[File:250px-MKDD_Birdo_Egg.png]] will produce the same image. Either option will work in creating an image.
Hopefully this information helps answer your questions. And no worries about the complexity of the problem.
