They look like cory eggs to me. My female spawns a lot, and I have tried all the tricks and have always ended up with fungus issues. The only thing I haven;t tried is to move all the fish out and let the eggs be, so they won't get eaten off the glass. Check the underside of any leaves you have (real or fake). Snail eggs are usually clear jelly blobs with several little clear/white eggs Look like champagne bubbles in clear jello...lol Cory eggs are firm single eggs that look white to tan. Who knows maybe you will get lucky and have some little cory fry very soon. I would be worried about the loaches sucking them right off the glass though.
The last time my female spawned I removed the eggs by clipping the leaves with the eggs on them and put them in a breeder with fine air bubbles under them and they still got fungus. I didn't try any of the meds to ward off the fungus and may try that next time. I was told the Malachite Green, but I was going to try pimafix instead because it is natural, but they got fungus before I could get some.
Good Luck!!!

P/S if you want her to spawn again try a 10% water change with a bit cooler water than normal. It mimics rainfall and triggers spawning in the cory's
