Phase 1 Recruits,
Congratulations on your progress so far. Soon we will be opening up Phase 2. In preparation for that, please discuss amongst yourselves and select a candidate from each of the 4 Divisions.
In the meantime, we can use your help in deciphering a strange series of photos sent in to our public contact.
The images are accessible at EPSILONIMAGES. Any information you can figure out will be useful.

Solution
Intersections
The intersection images names when sorted by Ave we get:
Intersection near the big apple
Remark: It seems that the puzzle was meant to be solved in the other direction —> First: Find the above right sentence —> Second: Determine that "Intersection.png" belongs to 1st Ave, "near.png" to 2nd Ave and so on. Should be a help in finding the right Intersctions.
The right order of the intersections:
| filename | Ave | St | letter |
|---|---|---|---|
| intersection | 1st | E 14th St | 14 = "N" |
| near | 2nd | E 5th St | 5 = "E" |
| the | 3rd Ave | E 23rd St | 23 = "W" |
| big | 4th Ave | E 12th St | 12 = "L" |
| apple | 5th Ave | W 25th St | 25 = "Y" |
Translating the Streets into letters 1 = "A", 2 = "B", … results in
NEWLY
Towers
This leaves the tower images names. Sorting them again into a menaingful sentence
vigenere PVKOWIUCTZD using names
And repetively using the tower names as vigenere keys results in:
PVKOWIUCTZD + COITTOWER (as Key) = NHCVDUYYCXP
NHCVDUYYCXP + NSEOULTOWER (as Key) = APYHJJFKGTY
APYHJJFKGTY + EIFFELTOWER (as Key) = WHTCFYMWKPH
WHTCFYMWKPH + SPACENEEDLE (as Key) = ESTABLISHED
leading to the final phrase:
NEWLY ESTABLISHED
