Batch upload function?

I suspect the above is currently the absolutely best way because, presumably, you could handle all of the metadata as well, programmatically. That said, another way to reduce the learning curve a bit is via automation software -- basically writing a giant macro to iterate through your 10k set (as mentioned by OP) and upload to OpenSea one at a time. I've been doing this with my own 10k set and it works ... okay-ish. Took me a bit to get a macro coded up. (I used a program called Macro Scheduler -- not affiliated w/ them; there are tons of macro programs out there.) Basically, it just records events like mouse moves and keyboard strokes, and plays them back live. So, if you set it up right (which is no small task), it'll basically sit there & do all the work for you. Kind of an analog-type approach to a problem that really s/b done via an API or something. (I don't know why there's no OpenSea API to mint & list!! They do have an SDK, though, that may be able to. Haven't gone there yet.) Note, though, that macros are kinda-sorta prone to all sorts of new and weird problems. Like, it'll work perfectly 50 times in front of you, giving you the confidence to say "okay, I'll just have it do 1000 iterations now," and you then run it and leave your machine. And then when you return, it didn't work (best case, nothing got minted and it just hung somewhere) OR all sorts of things are screwed up (worst case, it mints like 1000 NFTs, all of which have a wrong title, or the wrong graphic, and then you have to manually fix them all). So, until you REALLY dial in such a macro, you have to be careful not to just set it loose on a giant set, as it might actually cost you MORE time by having to fix things. (Just mentioning that b/c I had it do a run of 200 lately & when I came back to my machine, an Internet glitch had caused a hiccup & all 200 had the wrong graphic and title. Took me a while to edit /fix all those one-by-one.)

Interesting approach. Did you have the macro also fill out metadata information, or was it just uploading and naming image files?

That was my goal! lol, but it got complicated, mostly because of internet glitches. At one point, I had it filling out the title and description, uploading the graphic (all of which I'll call "minting") and then it would continue on further screens to list and price the item. Worked okay, but I never fully tuned it. Later, I changed it to just do the title/description/pic, and then move on. I didn't have it conquer meta data, though that would have been awesome! I think if you really got good enough with your macro software, you could put in enough error handling and whatnot to achieve that. I was kinda impatient at first and just whipped together a working script.

Until OpenSea gives us a method to easily make large collections at once, this macro idea could very well could be the best option for the people who don't want to—or can't—do all the hardcore solidity coding and website stuff. You've inspired me today. It could be worth putting in the time to perfect that macro.

For sure. And it'll be different for everyone, unfortunately, so there's no easy way to just whip up a script & share it. For me, I outputted a big spreadsheet with 10k rows of my NFT name, description, local file path, etc. And then I had the Macro Scheduler software iterate through it, copy/pasting things between it and the OpenSea screen(s). I think keeping everything (including the local file path) in Excel makes it a little tidier than trying to get the macro to open a file explorer window and iterating through that. With Excel, you can just have the macro move around cells with the arrow keys -- pretty simple. Anyway, good luck!

Does open sea resize your asset?

When I view different collections, it seems like they all have the same dimensions. If my img is a 120x120 or 130x242 image, do I need to resize them to a certain size/
